Are there any models of Finnish trains, preferably in 0 scale but if not, in any other scale?
Yes, there are, but limited editions, some are photo-etched brass kits, some are bodyshell molds on Roco underframe and some are 3D prints. For Finnish N scale 1:160 models ask www.n-club-finland.org and for Finnish HO scale 1:87 models ask www.fremo.fi but the expert manufacturers in both mentioned scales are www.mestarimallit.com...
Among other European O gauge projects myself I am designing currently Finnish passenger coaches (pikajuna, intercity) and Russian passenger coaches (RepinExpress, TolstoijExpress, TransSiberiaExpress) as frequently observed on the Helsinki Cetral Rwy.St.
